Warranty
If the paddlewheel flow meter is applied to a system with particles or crystallization (e.g. CuSO4), please do CIP (Clean-in-place) before installing the meter. Any damage related to not doing CIP will not be covered by the warranty.
The paddle device is made from ceramic material, which is built to last longer,but it is not impact resistant. The drop of the paddle set when disassembling or assembling, the rapid change of flow pressure (such as the switch of pump or valve), water hammer and the impact of foreign objects are not covered by this warranty.
It is recommended that users gradually start the valve system in order to avoid high water pressure change in a short period of time because it might damage the paddle. For example, start the pump inverter at lower frequency (ex:35Hz), and then increase the frequency after system has stabilized for a period of time.
Measuring range and service life:
The working flow speed range of this flow meter is from 0.15m/s to 10m/s, but high flow volume may cause a shorter life span for the paddle. It is recommended that the customer select the suitable pipe diameter, and a long-term flow speed of below 5m/s.
